Justin Bieber may not have been born when the United States government's so-called War on Drugs began, but he's apparently hoping to be around to see the ceasefire.

"shoutout to @UncleRUSH . gotta support him to #EndTheWarOnDrugs and show that we the youth have a voice. hashtag and support the cause," the 19-year-old pop star tweeted today in support of Def Jam cofounder Russell Simmons, who posted an online letter to the Obama administration urging him to implement "more creative criminal justice reform" (etc.) when it comes to drug users.

And Bieber, who used his Saturday Night Live hosting gig in February as a platform to apologize to his fans for smoking marijuana, isn't the only one helping to spread the word via Twitter, though we have a feeling the tweets have only just begun!

"Props to ->'@justinbieber: shoutout to @UncleRUSH . gotta support him to #EndTheWarOnDrugs and show that we the youth have a voice,'" tweetedSamantha Ronson.

"America spends $30K to incarcerate an inmate but less than $12K on a student! http://bit.ly/Xzq0UM #EndTheWarOnDrugs PLS RT!," addedDeepak Chopra.
